11 Claims. (Cl. SiS- 72) This invention relates to a photographic plate the loading device as seen onthe line 6-6 of and apparatus for loading the same into a Fig. 1. camera. Referring more particularly to the drawing, I0 In the operation of photographic apparatus it indicates a magazine unit of a camera., or the like, is desirable vto provide simple means whereby a which magazine is here shown in Fig. 1 as being 5 plate may be inserted within the camera without circular in section, and of tubular form to reremoving the camera to a dark room while it is ceive a photographic plate or disc II. For the being loaded. This is particularly desirable in purposes of use in'a declination indicator this such structures as oil Wellsurveying apparatus, disc is circular and'ilat, and is provided with a such as shown inthe co-pending application encoating of photographic emulsion on one or both 1g titled Declination indicator for Wells, Serial No. of its sides for use in taking photographic ex- 645,600, filed by John C. Hewitt, Jr., one of the posures. The magazine I0 is provided with a applicants herein, December 3, 1932, and in which transverse slot I2 for the purpose of receiving structure a photographic disc is inserted to record the photographic plate II and for permitting it 5 the declination assumed by the instrument in to pass from a loading device I3. The loading 15 well surveying. It is the principal object of the device comprises a Substantially Semi-circular present invention to provide a loading device saddle Il which is made to conformtothe contour adapted to be disposed in a loading position relof that portion of the magazine II) through which ative to a plate holder of a camera, or like photothe plate opening I2 occurs. Extending laterally o graphic structure, and also to provide a plate from the saddle I4 is a base portion I5 having 2o carrier which when installed within the loading a iloor I6 and a parallel upper wall I1. The device will make it possible for the photographic iloor I6 and the wall II are spaced from each disc to be released from the carrier and introother to form a passageway I8 which leads to a duced into the camera without possibility of leakslotted opening I9 occurring in the saddle I4 i5 age of a light which would tend to make a preand Communicating With slctted opening I2 of 25 exposure 0f the disc, the magazine III.

@it Fig. 6 is a View in. transverse section through cessed portion, El will lic understood Fmt H1e passageway I 8 is closed on its opposite sides and at its outer end.

It is also to be pointed out that extending upwardly from the body member I 5 are side anges 29 between which the hinged cover 23 seats when the cover is in its closed position. This provides a further light seal. 'I'he loading structure is adapted to receive the plate carrier 30, shown particularly in Figs. 4 and 5 of the drawing. By reference to Fig. 5 it will be seen that this carrier comprises a frame member 8| having al central recess 32 therein. This recess is of a configuration to receive the photographic plate I I and since the plate is here shown'as circular, the recess 32 is circular. The depth of the recess 32 issuicient to accommodate the thickness of the plate II. Attached to the frame member 3| is a sealing ap which comprises two folding portions 33 and 34 which are folded upon each other, and in turn fold down over the frame 3| and within a cover piece 3| toclose and seal the recess 32. The ilap portion 34 is formed with an extension 35 which, as shown in4 Fig. 2 of the drawing, projects outwardly beyond the meeting faces of the members I5 and 23 so that the aps may be drawn outwardly from their folded positions to release the photographic plate II.

In the operationl of the invention the photographicplate is positioned within the recess 32 of the frame 3| under conditions where exposure will not take place, and the flap portions 33 and 34 are folded and inserted beneath the cover piece 3| to cover the frame 3| and the photographic plate II seated in the recess thereof. It is to be understood that the flap portions are here shown as Amade of paper or other flexible material which -is opaque, but that if desired other closing means might be provided, such as an opaque plate or slide. 'I'he carrier with the film therein is then in the position shown in Fig. 4 of the drawing. The loading device I3 is then grasped in one hand with its cover 23 raised, or otherwise removed, after which the carrier with the film is positioned. between the side flanges 29 while resting upon the upper face of the wall I'I and the body member I5. The cover 23 is then folded downwardly to the position shown in solid lines of Figs 2 and 3 of the drawing. 'Ihe ngers of the hand of the operator may be placed upon the portion of the carrier which is disclosed through the opening 28 in the hinged cover to position the same. When the hinged cover is folded downwardly the carrier will be positioned Within the recess Yformed p in the hinged cover and which is bounded at its outer edge by a flange 36. This :flange cooper- 'ates with the side iianges 29 to seal the carrier completely within vthe loading device. In this assembled relation of the loading device I3 and .being drawn outwardly while allowing the iiap portions 33 and 34 to be pulled from their folded position, as shown in Fig. 2 of the drawingyto the position shown in Fig. 3 of the drawing, at which time these flaps will move from an obstructing position beneath the recess 32 of the frame 3|, and from between the frame 3| and the cover piece 3|'. By reference to Fig. 3 of the drawing it will be seen that when this has been accomplished the photographic plate or disc II will be free to fall from the recess 32, which ls in register with the opening 22, through the upper wall I'l of the body member I5. The photographic plate will then fall on to the oor portion I6, and will be within the slotted passageway IB. By inclining the film magazine Il! and the loading device so that the lm magazlnewill be lowermost it will be evident that the photographic plate will slide longitudinally of the passageway I3 and through the slotted opening I 3 and the slotted opening I2 of the magazine into the magazine Ill. Mechanism within the magazine will cause the plate to be moved to a position of photographic exposure, but will hold the photographic plate in a manner so that it will not be exposed to light passing through the slot I2. The structure of this mechanism is not a part of the present invention.

It will thus be seen that by the structure here disclosed convenient means are provided for temporarily enveloping and carrying a photographic plate to a point to where it is to be used, and that additional means are provided for readily removing the photographic plate from the carrier and easily loading the same into the magazine of a suitable piece of photographic apparatus.
